Unmasking the Hidden Tumours: Clinical and Pathological Insights into Appendicular Neoplasms

Appendicular neoplasms, although rare, represent a diverse group of tumours arising from the appendix, including adenocarcinomas, carcinoid tumours, and mucinous neoplasms. This review aims to synthesize current knowledge on the epidemiology, diagnostic approaches, and treatment options for appendicular neoplasms. We conducted a comprehensive literature search across multiple databases, identifying key studies that elucidate the incidence, clinical presentation, and histopathological characteristics of these tumours. The epidemiological data highlight a slight male predominance and variability in incidence across different populations. Clinical symptoms often mimic acute appendicitis, leading to potential diagnostic challenges. Advanced imaging techniques, including ultrasound and computed tomography, play a critical role in diagnosis, often supplemented by histological analysis. Treatment typically involves surgical resection, with chemotherapy considered for advanced or high-grade tumours. Prognosis varies significantly depending on tumour type and stage at diagnosis, underscoring the need for early detection and tailored management strategies. This review identifies critical gaps in the literature and suggests directions for future research to enhance understanding and treatment of appendicular neoplasms.
